LOCOMOTIVE STRUCTURE Application filed March 16, 1928. Serial No.262,127.

My invention relates to railway rolling stock and particularly tolocomotive structure, and consists in a novel arrangement of the use ofthe parts referred to without the labor and material required forseparately forming and assemblin them and also to eliminate thenecessity OI constant inspection of the parts and frequent tightening oftheir connections in order to maintain their rigid assembly. I

In the accompanying drawings which illustrate a selected embodiment ofmy invention Figure 1. is a side view of the front portion of the bed orframing of a locomotive illustrating a steam cylinder, steam supplychamber, boiler saddle, brake cylinder and lever, and brackets for thesame, pedestal,

dock plate, pilot beam, and coupler pockets Fi ure 2 is a top view ofthe framing member i lustrated in Figure 1 with some of the otherelements sectioned to better illustrate their structure, this sectionbeing taken on line 22 of Figure 3.

Figure 3 is a vertical transverse section taken on line 33 of Figure 1.

Figure 4 is a front elevation of one-half of the pilot beam and couplerpocket.

Preferably I combine most of the parts illustrated in a one-piececasting including a locomotive bed with side frame elements 1, connectedby transverse walls 8 and 9 which carry the boiler saddle 2. The castingalso includes the steam cylinder 3, steam supply chamber 4, steamexhaust passages 5, pilot beam 6, and coupler pocket forming elements 7The rear transverse Wall 8 has formed integrally therewith angularbrackets 10 for mounting the brake cylinder 11 which is separatelyformed and is of the usual construction. Ordinarily such cylinders aremounted on the top of the transverse members of the framing andtherefore are spaced farther from the boiler saddle and closer to thedriver axles.

Projecting downwardly from the framing member 1 and transverse walls 8and 9 is an integral bracket 12 on which the brake cylinder lever 13 maybe fulcrumed as indicated at 14. The lever 13 will be operated by asuitable connection 15 to the piston in cylinder 11.

This construction enables the brake cylinon, or GRANITE CITY, ILL NoIs,A conroder to be located closer to the boiler saddle than is possiblewith the usual mounting previously used,.and the brake lever may beoperated without interfering with the front pedestal structure 16.

While I show the saddle and the transverse member of the bed whichsupports the saddle as being formed inte rally with each other and withthe remaimier of the bed, the saddle portion could be made detachablewithout affecting the advantages derived from mounting the brakecylinder on the transverse member.

The integral formation of the pilot beam 6 with the bed or framingeliminates a large amount of machining and bolting or rivetingoperations, and the provision of webs or ribs at the center portion ofthe pilot beam to form the coupler pocket also saves considerable weightand eliminates much drilling and other machining and assembling labor.With this structure, the coupler pocket can be located partly to therear of the front walls of the pilot beam without weakening thestructure and this will result in less projection of the coupler beyondthe front of the pilot beam.

It is not essential to the use of other features of my invention thatthe coupler pocket be formed integrally with the pilot but the pocketmember could be formed separately and attached to the front face of thesaid saddle.

21. A one-piece locomotive bed casting having a pair of steam cylinders,steam passages and a pilot beam' formed integrally therewith, said pilotbeam extending laterally from said bed.

22. A one-piece locomotive bed casting having a pair of steam cylindersand a pilot beam formed integrally therewith, said pilot beam extendinglaterally from said bed in front of said cylinders.

23. A locomotive bed having an integral horizontally disposed steamcylinder and having an integral pilot beam projecting laterally of thebed in front of said steam cylinder.

24. A locomotive bed including horizontally disposed steam cylinders,pedestals, and a pilot beam projecting laterally from the bed and infront of said cylinders, all integral with each other.
